Asphyxiaphilia is a paraphilia where sexual arousal or orgasm depend on the deprivation of oxygen as a result of self-strangulation or partner induced strangulation. The point, for the asphyxiaphiliac, is to be deprived of oxygen up to, but not including, the point of unconsciousness. It is considered a paraphilia due to the dangers of death by strangulation.
